Abstract
The present disclosure provides a multi-view single-frame phase demodulation method based on a structured light field and related components. The method includes: constructing an LFDNet neural network; collecting a data set by a structured light field system and training the LFDNet neural network to optimize the LFDNet neural network; and inputting a multi-view fringe image to be predicted into the optimized LFDNet neural network, outputting numerators and denominators of multiple views, and calculating the numerators and denominators of the multiple views via an arc tangent function and obtaining wrapped phases of multiple views. The present disclosure combines deep learning with the characteristics of multi-view imaging of the structured light field system, utilizes a neural network to learn a mapping relation from the multi-view fringe image to the numerators and denominators, and has the advantage of implementing single-frame high-precision phase demodulation of multiple views of a light field through one prediction.
